Sizing a central AC system in Love County starts with what the equipment will actually run against, season after season. 97 severe weather events were recorded in Love County, Oklahoma between 2015 and 2024. At that rate, severe weather is part of the normal operating environment for any system installed here, which means a contractor has to account for sustained load when they spec the unit, not just peak summer temperatures. An undersized system catches up slowly, strains harder, and wears faster. A contractor who quotes without weighing that record is quoting for a different county.
Ductwork laid out for older cooling equipment carries assumptions about airflow and routing that a modern central AC system does not share. Half the homes in Love County, Oklahoma were built in 1984 or earlier (2020-2024 ACS 5-year). A contractor installing new equipment in stock like this has to assess whether the existing duct runs, their sizing, and their condition will actually move air the way the new unit requires. If they will not, the duct work becomes part of the job before the electrical service gets priced. What the house already contains, and whether it can carry what is being put in, is what sets the scope.
What a Central AC System Includes
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and the condenser coil. Inside, the air handler or furnace-and-coil combination lives in a closet, attic, or basement and moves air across the evaporator coil. These are the two main pieces a contractor puts in place.
The thermostat mounts on an interior wall and is what the homeowner uses to control the whole system. The refrigerant line set runs between the indoor and outdoor units, and the condensate drain line carries moisture out of the house. Both get routed during the same installation.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.

What the Installation Actually Looks Like
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
What Love County, Oklahoma Requires for HVAC Installation
An Oklahoma mechanical licence is valid statewide, and a contractor licensed by a local authority who works only in that locality is not required to hold the state licence at all.
Oklahoma requires a Construction Industries Board licence for mechanical work: nobody may do or advertise mechanical work as a journeyman or contractor without the right licence.
Severe Weather History in Love County
Oklahoma weather puts real demands on cooling equipment, and Love County gets its share of what the region delivers. How hard a system has to work over its lifetime is a local question, and the record here is part of the answer.
